1. Technical Field
This exemplary disclosure generally relates to key button structures, and particularly to key button structures for portable electronic devices.
2. Description of Related Art
With the development of science and technology, portable electronic devices such as mobile phones and personal digital assistants (PDAs) are now widely used. Consumers may enjoy the full convenience of the portable electronic devices almost anytime and anywhere. The portable electronic devices usually include key button structures welded to housings. The welding makes it difficult to detach the key button structure for repair or reassembly.
Therefore, there is room for improvement within the art
Many aspects of the exemplary key button structure can be better understood with reference to the following drawings. The components in the various drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary key button structure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the diagrams.
In this exemplary embodiment, the key button structure is applied to a portable electronic device such as a mobile telephone. The mobile telephone described herein is a representation of the type of portable electronic device that may benefit from the exemplary embodiment. However, it is to be understood that the exemplary embodiment may be applied to any type of hand-held or portable device including, but not limited to, the following devices: radiotelephones, cordless phones, paging devices, personal digital assistants, portable computers, and the like. Accordingly, any reference herein to the mobile telephone should also be considered to apply equally to other portable electronic devices.

The second housing 33 has substantially the same shape and size as the first housing 31 such that the second housing 33 can be tightly assembled in the first housing 31. The second housing 33 includes an assembling opening 331 defined therethrough corresponding to the window 3111 of the first housing 31. A latching slot 3311 is recessed in and adjacent to one end of the second housing 33 and communicates with the assembling opening 331 corresponding to the latching block 231 of the fixing member 20. Two assembling slots 3313 are recessed at two sides of the second housing 31 and communicate with the assembling opening 331 corresponding to the two elastic arms of the fixing member 20. The second housing 33 further includes a resisting block 3315 extending outwardly therefrom opposite to the latching sot 3311 and accommodated within the assembling opening 331. The resisting block 3315 includes two fixing holes 3317 defined through corresponding to the two fixing posts 236 of the fixing member 20 respectively.
